How Did I Test The Best Generators For Home Backup

These are the tests I did to arrive at the list of the best generators for home backup:

Power Reliability Test

For each generator, I listed in this article I made sure to fill their tanks, turn them on and let them run with a few electric devices attached until empty.

If the generators lasted the time listed in their product descriptions, on separate and repeated occasions, then I would continue with further testing.

Portability Test

This test was easy, if the generator was portable enough to be easily moved from one place to another, then it would pass the test.

Durability Test

The durability test was the hardest as I had to stress test each generator for a long period of time, which cost me a lot of money.

However, it did give me enough information to comfortably recommend what generators were made with reliable materials that would last, at least, a few years.

Must-Have Features For The Best Generators For Home Backup

For those interested in saving a lot of time, these are the attributes generators for home backup should have.


The last thing you want when buying a generator is one without enough power to give a steady stream of electricity to various electric devices at the same time.

I mean, at the end of the day, you’re trying to give power to a house, right?

Thus, looking for a generator with enough wattage to charge and power various devices is first on my list of must-haves for generators.

Reliable Performance

You might think: “well, most of the generators I’m looking at should be safe to power most of my essential gadgets, regardless of the exterior conditions (i.e. hot or low temperatures). I mean, look at those prices!”

Well, the truth is not that simple as most expensive generators for home backup don’t necessarily provide a steady power source.

This is why I recommend looking for generators that offer reliable performance with a regular voltage as this is the easiest way to make sure that your equipment is not going to be wrecked by an electrical surge.

Fuel Economy

Well, this is an easy one. Fuel is expensive, I mean really expensive, we all know it.

Getting a generator that offers a strong fuel efficiency is the best way to make sure that you won’t go broke when powering your household devices.

Low Noise

A common problem with home backup generators is that they are really noisy.

I mean, even though it’s not a big issue, I really like to use generators that run around 52 to 60dba of noise. As this is the sweet spot between power and noise.

Portability & Compactness

For those people looking for a generator for home backup for camping, RV, or outdoor activities, then I think adding portability as a must-have feature is smart.

If the generator you’re looking at weighs about 200 and 250 lbs then I think it’s compact enough for these circumstances.


Nobody wants to see their hard-earned money wasted on a generator that doesn’t last more than a few months, right?

Well, if you don’t want to suffer that frustration, then going for a generator manufactured by a recognizable brand, that uses quality materials in their products and that has good reviews is a good start.

Frequently Asked Questions

Do Generators For Home Backup Need To Be Maintained?


Just like any car with a motor, a generator needs regular oil and filter changes to make sure that no problems will come up in the future.

What’s The Advantage Of An Aluminum Enclosure In A Generator For Home Backup?

When it comes to a generator for home backup, the last thing someone wants is to get one that doesn’t last more than a few months.

This is why aluminum enclosures started to appear in current generators as this material has the advantage of being rust and corrosion resistant which makes it perfect for humid environments and the unstoppable pass of time.

Pro-tip: For those interested in skipping getting an aluminum enclosure (or not) and running the generator indoors, make sure to read this article.

Can A Generator For Home Backup Replace Utility Service?

This is an easy one: NO

Fuel costs are really high in comparison with the utility bill mainly because you have to pay the fuel on your own while the electric bill is divided by thousands of customers that live nearby you.

How Do I Correctly Choose A Generator’S Size For My Home?

The process for measuring the size of the generator you need for your home backup is simple:

  • Make sure to measure how much electricity (wattage) your essential devices need to run for a day or a half of a day
  • Think of how long you will need or want the generator to provide electricity
  • Calculate the level of wattage in total you will need to power all your household equipment
  • Read the specifications of every generator and choose accordingly

What Type Of Oil Should I Use To Maintain A Generator For Home Backup?

You will have to read the user’s manual to get an exact answer.

However, it is safe to say that a SAE rated oil that meets the requirements for fuel engines should be fine to use as oil for your generator for home backup.

In my case, I use the SAE 30, both with my generator and lawnmower.

What Happens If The Generator Gets Overloaded?

Nasty things can happen if a generator gets overloaded. I mean it could:

  • Ruin your household equipment and devices
  • Ruin the generator itself
  • Catch on fire
  • Break and release hazardous gasses or just leak fuel
  • Make you lose thousands of dollars on repairs

The best way to make sure that this does not happen is by doing two of the following things:

  • Calculate the needed wattage: Make sure that the household devices you will hook to the generators at the same time need the amount of wattage your generator offers
  • Get a generator with overload protection: This is key. Nowadays there are a lot of brands that offer overload protection. What it does, is basically turning off the power in the generator before reaching an electric overload, which avoids all the headaches I previously mentioned
